    Rocket Lab postpones Neutron rocket maiden flight to 2027 on dome defect

    Question

    Rocket Lab postpones Neutron rocket maiden flight to 2027 on dome defect

    Direct answer

    Rocket Lab has officially rescheduled the maiden launch of its medium-lift Neutron launch vehicle from the fourth quarter of 2026 into 2027. Engineering inspections identified structural manufacturing defects within the carbon composite dome of the first-stage propellant tank. The delay pushes out the commercial monetization timeline for the medium-lift architecture, sending the stock down 10% to $53, extending its drawdown to 65% from its May record.
